Report of the Special-purpose Committee on Virtual Participation in the Nomenclature Section

The Special-purpose Committee on Virtual Participation in the Nomenclature Section was established by the XIX International Botanical Congress (IBC) in Shenzhen, China in 2017, with the mandate “to investigate the possibility of and mechanisms for virtual participation and voting in the Nomenclature Section of an International Botanical Congress via the internet” and to report to the XX IBC. The wide access to the World Wide Web and availability of software for virtual meetings makes the possibility for virtual (online) attendance and voting at a Nomenclature Section seem attainable and advisable. In order to make informed recommendations, we discussed various aspects of online attendance and voting, such as: who should be able to observe?; what would qualify a person to cast institutional votes and personal votes?; if the accumulation of institutional votes should be allowed by an online voter; registration of online voters; how costs would be covered; and recommendations for online attendees. This report provides a synthesis of our discussions and is necessary for interpreting the proposals of this Special-purpose Committee to change aspects of Div. III (Provisions for governance) of the Code (Landrum & al. in Taxon 70: 1397–1398. 2021). This report and those proposals should be consulted together.Fil: Landrum, Leslie R..

Taxonomic Notes on the Genus Crataegus (Rosaceae) in Turkey

The Turkish Crataegus taxa were investigated using morphological, palynological, and anatomical characters. A new series (Crataegus Section Crataegus Series Peshmenia), two new species (Crataegus peshmenii and Crataegus christensenii), and one variety (Crataegus rhipidophylla var. kutahyaensis) are described. Furthermore, Crataegus x browicziana has been assigned to Crataegus rhipidophylla with a new status. Illustrations of the described taxa and their distribution map are also given. The lectotype for Crataegus yaltirikii is designated here. (c) 2007 The Linnean Society of London.WoSScopu

Astragalus Ihsancalisii (Fabaceae), A New Species from Erzurum Province, E Turkey

Astragalus ihsancalisii Donmez & Ugurlu (Fabaceae) is described as a new species from Erzurum province in E Turkey. The new species belongs to A. sect. Incani DC. and is similar and possibly related to A. glaucophyllus Bunge and A. guzelsuensis F. Ghahrem. & al. from Turkey and A. siahcheshmehensis Maassoumi & Podlech from Iran. Astragalus ihsancalisii is clearly distinguished from those three species by flower number per raceme, bract size, pedicel length, standard length and legume beak length, among other characters. Diagnostic characters are given and their taxonomic importance is discussed. Photographs of A. ihsancalisii in the field are presented. In addition, SEM micrographs of leaf and legume surfaces of the new species and A. glaucophyllus and A. guzelsuensis are provided for comparison. The conservation status of A. ihsancalisii is also assessed according to field observations.WoSScopu

Morphological and molecular data on a new species of Polygala (Polygalaceae) from Turkey

WOS:000998338000001Polygala fadimeana Dönmez and Çeçen is here described as a new species from the inner part of the Taurus mountain range in Turkey based on morphological data and its phylogenetic position is discussed based on molecular data. This new species is confined to limestone rock walls and is morphologically distinguished from P. kurdica and P. peshmenii by smaller plant size, nearly glabrous leaves, enrolled inner sepals, white colour crest, and other minor diagnostic features. However, a multi-locus chloroplast phylogeny (trnL-F and rbcL) including accessions of the new species and related taxa of Turkish Polygala revealed a close relationship to P. pruinosa and P. supina. The taxonomic relationship among the new species and P. kurdica, a poorly known species from Zagros Mountain range, and other closely related species such as P. pruinosa, P. peshmenii and P. supina are discussed. The new species is assessed as critically endangered (CR) based on current knowledge and the distribution of the new species and related taxa is mapped
